CLUTCH-.flLAMPING LEVER.

Application filed October 21, 1922. SerialNo. 596,076. V K

To all whom it may concern:

Be it known thatLCL'ARnNon G. VOOD, a citizen of the United States, residing. at

specification. V i

The invention relates to clutch clamping levers of the type used in connection with clamping plates of clutches, and also the type which is provided with a cam nose for cooperating with a bevelled surface for op? erating a clutch, and has for. its object to provide a lever of this character formed from stamping thereby obviating machincost of the lever to a minimum.

A further object is to provide a clamping ings, the cam nose of the lever being formed by inwardly extending engaging flanges carried by the registering stampings. The stampings re preferably se- 2 cured together by spot'welding adjacent the nose end thereof and by the usual pin for engaging a thrust collar.

With the aboveand other objects in view theinvention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawing,described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing Figure l is a front elevation of the clampin lever.

igure 2 is a side elevation of the clamping lever.

Figure 3 is a detail perspective view of the upper end of one of the clamping levers.

Referring to the drawing, the numeral 1 designates a clamping plate lever, which lever is formed from sections 2 and 3. The sections are stamped from single sheets of material and are provided with bends 4 and 5. The sections 1 and 2 are in abutting-en gagement as shown in Figure 1 thereby forming the arm 6 of the lever. The lower ends of the stamped sections 2 and 3 are manner.

lever formed from two registering stamp secured together'by means of a pin 7, the end 8 of which is received in a conventional formof channel of'athrust collar. The upperfends of thestaniped sections 2 and'3 are provided with "offset portions 9 and '10 in parallel relation to each other, which portions are provided with apertures 11 for, the receptionof pivot pins after the clamping-plate lug has been: disposedbetweenthe oi'fset portions. The-clamping plate lug 12 is carried "by a conventional form of clamping plate 13,

*Oflset portions 9 and 10 are provided which is operated in the usual with arms 14, which arms. terminate in in jwardly extending flanges 15,, which abut ing parts of this character and reducing the each other and form the =nose16 of the clamping lever, said nose being preferably eccentric to the pivotal point of the lever. After the pin 7 has been secured, thereby securing together the lower ends of the stamped sections 2 and 3, said sections are then spot welded together at 17. Each section 2 and 3 is stamped from a single sheet of metal, preferably in a single'operation, and consequently it will be seen that the entire lever is formed with the minimum amount of labor at the minimum cost, and that machining is obviated.

The invention having been set forth what is claimed as new and useful is 1. A clutch clamping levercomprising an arm, a nose carriediby said arm, said lever being formed from registering stamped sec-1 tions. r

2. A clutch clamping plate lever, said lever comprising an arm, a nose carried by said arm, said lever being formed from registering stampings, said nose being formed 7 p from inwardly extending integral lugs car-. ried by the registering stampings.

3. A clutch clamping plate lever, said lever comprising an arm, a nose carried by said lever, said arm and nose being'formed from registering stampings. 4. A clutch clamping plate lever, said lever comprising an arm, a camming nose carried by. said lever, said lever being formed from registering stamping's, the arms of the stampings being secured together, the upper ends of the arms being pro vided with ofiset integral ears formed with the stanipings, said ears being provided with outwardly extending portions, said outwardly extending portions terminating in ears extending towards and abutting each 5 other and forming the nose of; the lever.

5. A "clutch clamping Fplate lever,v said lever being provided with a curved arm, a

nose carried by said lever, said lever beingformed from registering stanipings, means for securing said stampings together, said nose being formed from inwardly extending ears in alignment with each other. a

In testimony whereof affix my signature.
